Abstract:
A discrete tapering interconnection is disclosed that forms an interconnection between a first electronic circuit and a second electronic circuit within an integrated circuit. The discrete tapering interconnection includes a first set of multiple parallel conductors situated in a first metal layer of the metal layers of a semiconductor layer stack and a second set of multiple parallel conductors situated in a second metal layer of the metal layers of the semiconductor layer stack. The first set of multiple parallel conductors effectively taper the discrete tapering interconnection as the discrete tapering interconnection traverse between the first electronic circuit and/or the second electronic circuit. This tapering of the discrete tapering interconnection can be an asymmetric tapering or a symmetric tapering. The second set of multiple parallel conductors is arranged to form various interconnections between various parallel conductors from among the first set of multiple parallel conductors.
